Proposition 19 Demystified: Moving, Inheriting, and Your Property Tax Bill Proposition 19 is a California ballot measure that has been effective since 2021 and reshaped two areas of property tax law. Parent-child and grandparent-grandchild transfer exclusion The property must have been the parent’s primary residence, and at least one child must move in and make it their own primary residence within one year. The child also needs to file for the Homeowners’ Exemption within that first year and submit the Parent-Child Exclusion claim with the county before the deadline. Miss those requirements, and the tax savings may disappear. Previously, a parent could pass a home to their child, and the child would keep the parent’s low property-tax-assessed value no matter what they did with the property—live in it, rent it out, or sell it. Prop 19 narrowed this significantly:
- The child (or grandchild, if the parents are deceased) must move into the home as their primary residence within one year to get any exclusion.
- Even then, the exclusion is only full if the home’s current market value is at or below the old assessed value plus $1 million (adjusted periodically for inflation). Above that threshold, the excess gets added to the assessed value — so there’s a partial step-up in basis.
- Rental properties and vacation homes lost this break entirely (unless converted to a primary residence)—inherited investment or second homes now get reassessed to full market value on transfer.
- A similar, though more limited, exclusion still exists for family farms.
Base-year value transfer for seniors, the severely disabled, and disaster victims
- Homeowners who are 55+, severely disabled, or whose home was destroyed by a wildfire or other declared disaster can sell their home and transfer their existing low assessed value to a new home anywhere in California, regardless of the new home’s price (if it costs more, the difference is added to the transferred base).
- This can be used up to three times (previously it was a one-time benefit in most cases).
- Before Proposition 19, this only worked between certain counties that had mutual agreements — it was a patchwork. Proposition 19 made it work between any county in the state.
Every family’s situation is different, and the details matter. Planning ahead can mean the difference between keeping a valuable tax base and losing it. If you’re preparing to transfer a family home or need financing for a sibling buyout, please contact Bluefire Mortgage Group at (760) 930-0569.
